Abstract

L'invention concerne un oscillateur à fréquence réglable, qui comporte une large gamme d'accords pouvant réglée par une tension ou un courant. On obtient un accord maximal par courant de retour, en effectuant un déplacement de phase d'un signal de retour d'environ 90 degrés par rapport au signal d'oscillation de sortie, qui est produit de manière interne par l'oscillateur à fréquence réglable. La fréquence d'oscillation du signal d'oscillation de sortie est linéairement réglable sur toute la gamme de fréquences de fonctionnement. L'oscillateur à fréquence réglable est également mis en service comme oscillateur en anneau et/ou oscillateur télémétrique.
